N normal phenotype
neoplasm
increased mammary gland tumor incidence ( J:178842 )
• in all mice by 500 days
increased tumor latency ( J:178842 )
• development of palpable tumors in the mammary gland is delayed 3 to 4 months compared to in Ccnd1tm1Wbg/Ccnd1+ Tg(MMTV-PyVT)634Mul Tg(TetO-Ccnd1T286A)11233Kuw mice
• however, latency is the same as in Ccnd1tm1Wbg/Ccnd1tm1Wbg Tg(MMTV-PyVT)634Mul mice

endocrine/exocrine glands
increased mammary gland tumor incidence ( J:178842 )
• in all mice by 500 days

integument
increased mammary gland tumor incidence ( J:178842 )
• in all mice by 500 days
